Sfiyooifleotion of Letters Patent. I Application filed June 24, 1am.-su-iirm. 0,518.

To all whom it maycomem: Be it known that I Louis-D.

Lnwxm', a citizen of the United rovenients in Flushing Devices for.Waterlosets, of which the following is a full, cleanand exactdescription, reference being had to the acco npnn ing drawings,forminiipertof this speci cation.-

, y invention relatesto o flushin device operated by an. arm whichdepends from -the hin ed seat of ,the closet bowl when-the seat' is eressed so as tomovenva'lve rearward, for ieflpm pose of nd'mittingwaterto the flushing tank and to be of water delivered from the flushing tankto the bowl when the seat is released whichmoves the valve forward,inorder-thni the bowl may be flushed while the [low of water i to thetank is discontii'iued.

My invention has for= its object tin: productioirofn scinmle andefficient flushing doviee of this character, in whicl'rthe. lmits areso'oonstructed that the entire valve stem and its valvesinay bewithdrawn from the valve shell at its forward end, when there isoccasion for such withdrawal; without anyneeessit-y oi detaching thevalve shell from tlioleloset bowl-and its other connections;

A further object ofmy-mvention is to provide a relief vent between theehnmherdd which the snpply eontrollmg valve'n )crzites' and the writersupply connection, or the mupose of obviating the ocenrrence of ulU-sllvi iomng action at the-rear of said valve when the closet seat isoccupied, and ermitting ready movement oi the valve in the stem 'hywhich ibis carried when iside.

In tl'ie'outer wn'l] tates ofAmerica, and t resident of the city ofEdwardsvilIe; inthe county ofMadison and State of llllinois have invented certain new .and: usefulInioperated by the force l1 fragment, of the seat- I of said rimis aniiperture Diand in the inner wall of said rimis on apertnreE, saidogerturee being designed to receive portions 0 the valve device tobehereinafto'r do scribed.

F is a. closet seat that is hinged to a suitable support and surinountsthe bowl A, and from which de wnds an arm G bai' i'n n' utility-thatwill hereinafter set forth.

H is a'woter supp pgae. I is a flushing tom 2: opted to receive a suppl1of winter and which, is closed to prerent e escape of water therefrom,in orden that whe'niw iter is admitted to the tank the air presenttherein-will be compressed.

J is'n flushing pipe. leading to the flushing tank. The parts thus fardescribed are known to be old and no invention per se is herein claimedfor them.

l designates the shell of my valve device which is attached to the rimo'fflhe bowl A and is interposed between the lvuter sup 1} .pipe H andthe flushing pipe J.. This vs. \e

shell is provided at "its forward end with a and. enters into thechannel. of the rim ofthe bowl A and terminates in a: reduced neck 3located within-the channel and 0011- "tniningranuil perforations 4. forthe escape of water from: the interior of the valve shell to the channelin the bowl rim as will herein after appear; It will be observer] thatthe ulined apertures D and E in the rim of the bowl .urenpproxii'rmielyof the some dimmoier.

nipple 2 which'extemlsueross the outer wallflso of the l'mshing. The nutis provided with a central aperture 9 that receives the forward end ofthe valve stem, to be presently more particularly referred to.

10 is a cup leather that is seated between the nut 8 and the diaplnragin7. At the rear end of the valve shell 1 is a tubular arm 1 that isclosed at its rear end by a nut 11 having an internal guide-way 12. Atthe lower side of the tubular arm of the valve shell is a dependingnipple 1, to which the water supply pipe H is connected, and at thejunction of said depending nipple and the body of the shell is aperforated diaphragm 1".

1. is a tubular born that projects upwardly from. the body of the valveshell, and to which the flushing pipe J is connected.

13 designates the valve stem of my device operable in the valve shell 1,and which carries a forward valve 14 movable in the nipple 2 and itsneck 3 and a rear valve 15 that is movable in the tubular arm 1 of thevalve shell. The first mentioned forward valve serves to control flow ofwater from the chamber of the valve shell to the channel. in the rim ofthe bowl A, and the other or rear valve serves to control the flow ofwater from the supply pipe to the valve shell chamber. The valve stemhas" a forward extension 13' that is operable through the cup leather 10and the nut 8 in the bushing 5, and in the recessed end of which isseated an anti-friction ball or a roller 16 which receives theengagement of the depending arm G, carried by too seat. l oi the watercloset. The valve stem also has a rear extension or wide member 13 thatis operable in the nit e-way' inthc rear nut 11, and is preferablysurrounded by an expansion s ring 17, which is of service in returning'1: 19. valve stern in a forward direction in the event of the pressureof the flush water directed against the valve 14, which is larger thanthe rear valve 15, bein insufficient to move the valve stem. forwar ly,after it has been operated through the medium of the water (lcset seat.

18 designates a relief ventduct or by-pass, leading from the chamber inthe rear tubu' lar arm 1' of the valve shell to the depending nipple 1,that has connected to it the water supply pipeH. This relief vent ductis of very material service in my valve device in permitting the escapeof water from the chamber in said valve shell arm at the rear of thecvalve 15, for the purpose of avoiding the occurrence of a water cushionat the rear of'said valve, which would render itdifiicult for the valvestem to be moved uon its receding stroke under the F the water closetseat when said seat is depressed. By providingthe relief vent duct, theair and any water that may have entered into the chamber in the tubulararm l back of the valve 13, capes from said chaml'ier as the valve movesrearuuirdly and is forced into the water supply coni'iections.

In the practical. use of my valve device, the operation is as follows: When the parts of the valve device are in the position shown in Fig. II,the flushing tank is filled with water which is under water column. andair pressure, due to the compression of air in the tank above the water.W hen the arts are as shown. it is to be assluned that t e seat is in adepressed position and occupied. Then, when the seat is relieved ofrestraint, the water is forced from the "flushing tank through theflushing pipe and exerts its force against the forward valve 14 which,as previously stated, is larger than the rear valve 15, thereby causingthe valves 14 and 15 to be carried with the valve stem 13 to thepositions indicated in vertical dotted lines Fig. 11. The forward valvebein at this time carried to a position in front 0 the perforations inthe nipple neck 3, the flush water readily passes through saidperforations and then through the perforations fi in the bushing 5 andentersthe channel in the rim of the water closet bowl to esca etherefrom into the interior of the bowl t r flushing action. Upon thewater closet seat being again depressed, its arm G acts against theforward extension of-the valve stem with the result of forcing said stemrearwardly together with the valves carried by it; As the rear valve 15moves rearwardly, the perforated diaphragm 1 at the top of the depend:ing nipple 1' of the valve shell is uncovered and a supply of water ispermitted to pass from the supply pipe H into the chamber of the valveshell and flow therefrom upwardly to the flushing tank for the purposeof replenishing the supply therein for service in.

the same manner as that previously described when the Water closet seatis freed from restraint.

I desire to direct particular attention to the-fact that the opening inthe valve stem incasing members of my valve device fittedto the run ofthe water closet bowl is of such dimensions as to be equal to or greaterthan the transverse dimensions of any part of the valve stem or thevalves and their appurtenanccs carried by the stem and consequently whenthe not 8 which closes the foremost valve stem incasing member isremoved, the stem of the valve and all of its appurte readily csnancesmay be readily withdrawn into the water closet bowl without thenecessity of makin r disconnections of the valve casing from t e bowl orfrom the water conducting p es attached to such casing. I thus pro- Vlte. for the removal of the valve stem and its valves with a minimum oflabor wheneveril; is necessary to make repairs in such parts 'or to'substltute new parts for those which have become unfit. for further useand avoid all injury to the valve casing antl its connections whichfrequently occurs in valve devices of like character that must beseparated from their connections previous to the removal of the valvesand valve stems for repairs or renewal of parts. i
